Vintage Diesel Model Airplane Engine, Unknown Manufacturer, Nice Condition

Description

Vintage Diesel Model Airplane Engine. This is a mystery engine, there are no markings or numbers on this engine. I thought it was a little unusual, the way there is no separation of the case and the fuel tank. It turns over fine. Looks in good condition. I do not know where it was manufactured or by whom. It is certainly over 30 years old. I cannot even tell you the displacement, maybe 1.0 cc??? Cannot say if it would run.
Please look at the pictures, they are the best description of what I have. I will be happy to answer any questions. I will combine shipping.
Please take a minute to look at the other engines I have listed. Each is quite nice and I don't think any of them come up for sale very often.
Shipped with USPS Priority Mail.
I will only ship within the Continental United States.
